In-Dash Receiver Specifications

Receiver Size

Single DIN: 1 DIN dimensions will work with all single DIN installation kits we have to offer. Single DIN radios are the most common size for after-market stereos.

Single DIN slot with flip-out screen: The DIN stereo includes a retractable, flip-out screen. Before purchasing, make measurements to be sure there is no interference with dash accessories such as A/C vents or shift levers.

Single DIN slot with a larger face: Standard single DIN size, but the display is larger then the standard single DIN size. Due to the nature of the larger face, problems may arise when installing in particular vehicles. These stereos are great for single DIN slots where you want a larger screen.

1.5 DIN: This size is very uncommon in vehicles, however this size opening is most commonly found in Chrysler and Chevrolet vehicles.

Double DIN: Approximately 4-inches in height, this size is becoming more common every year. Prior to 2000, this size was typically only found in Japanese vehicles such as those made by Honda or Toyota. Now, it is becoming more popular for many vehicles to be fit with a Double DIN opening.

Single DIN
Faceplate Security

Detachable / Removable faceplate security: The most common anti-theft feature. It allows you to take the faceplate with you, thus disallowing operation, which deters theft.

Security Codes: Mainly a feature in high end video units which do not have a detachable face / screen. Once the unit is uninstalled (or stolen), a security code (or PIN) is required upon reinstallation. Though you no longer have your unit after the theft, the thief also does not have your security code, which makes the unit useless. The hope is the thief knows which units have security codes and he/she chooses not to steal your unit because of the security code.

Ghost technology: This is not commonly used, but can be found primarily in a select number of 2004-2005 head units. It creates an illusion that no unit is installed by appearing completely black when turned off. Potential thieves may steer clear because it appears as though no head unit is installed.

Anti-theft covers: Similar to ghost and hiding faces because they only create an illusion that the face/unit is not in place.

ESN: Stands for Electronic Serial Number. Allows the disabling of the radio and allows tracking if it is stolen.

None
Motorized Faceplate
Some in-dash car stereos feature a motorized faceplate that moves to expose a CD or DVD slot. This is a convenient feature that allows the front display to be larger and easier to read. The positioning of the monitor gives you control over the angle you would like to view information on the stereo.
No
Remote Control
Allows control of specific features and functions from a remote control. Typically they are used to prevent button wear on your radio, or to allow easier navigation of menus.
Yes
Peak Power Output
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage occurring. Often times this maximum is achieved during a brief musical burst, such as a drum accent, or low bass hit.

Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison.

52 watts x 4 channels
RMS Power Output
The amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS rating, the louder and cleaner your music sounds. The RMS output figure is much more accurate than the peak rating when comparing products.
17 watts x 4 channels
Preamp RCA Outputs
RCA outputs, commonly known as preamp outputs, allow you to connect one or sometimes multiple external amplifiers. An in-dash receiver will commonly have one, two or three sets of RCA outputs that can be used to connect external amplifiers and other components. One pair of RCA outputs will typically provide a full range signal that can be used for most subwoofer or speaker amplifiers. Two pairs of RCA outputs can typically be configured as four full range signals, or also as two full range and two subwoofer signals. Three sets of RCA outputs will almost always produce four speaker signals and two subwoofer signals for use with multiple amplifiers.
2 Pairs (Front and Switchable Rear/Subwoofer)
Dedicated Subwoofer Preamp RCA Output
A dedicated output that has a built-in low-pass crossover for specific connection to a subwoofer amplifier that powers a low frequency driver, typically a subwoofer.
Yes
Built-In Equalizer
The number of graphic or parametric equalizer bands the stereo receiver is equipped with. The more EQ options, the more you will be able to adjust your music to your liking.
EQ3
Display Type
The type of display on your receiver refers to the monitor that is used to display the source information such as song names, radio stations, or track times.

Dot-Matrix Text Display: A simple display which uses dots in specific illuminated color(s) to light up and form letters or numbers that are displayed on the receiver.

Graphic or Motion Display: Typically found in mid to high-end receivers and give your text information and receiver more life by adding motion, backgrounds, or multiple colors to your display. There are types of graphic displays such as 3D Graphic, Motion, and OEL (Organic Electroluminescent) displays. They can range from one color to full color displays and typically allow you to select from one of many built-in animations, background images, screensavers or other graphics to enhance your experience and add an extra bit of personality to your system. Some units also come with software that allow you to load your own customizable pictures or animations.

LCD Monitor Display: Can be as small as 2" or as large as 10". Some LCD displays are motorized for angle adjustment. LCD monitors display full motion video playback as well as your standard text such as track status, radio station information and more depending on the receiver's features.

Dot-Matrix Text Display
Display Color
The display color refers to the color of the text and or graphics on the receiver.

Multi-Color: When more than one color is on the display, for example one part of the text is white, while the other part is blue.

Variable-Color: The display colors can be changed by the user. If the default color of text/display is blue for example, the user can change the settings to where the color turns to red. Variable color displays are typically described in detail in the item's description.

TFT-LCD Display: In-dash receivers with a video screen that display multiple colors and often times video such as DVD, navigation or other video sources.

White
Button Color
Refers to the color of the physical buttons on the unit.
Switchable Blue and Red
CD Signal-to-Noise
CD Signal-to-Noise Ratio is a key specification that is often overlooked by newbies. The CD S/N Ratio measures how well the CD player silences background noise. Higher ratings in decibels (dB) indicates less noise, and generally a cleaner signal.
100 dB
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Yes

Playback Features

AM/FM Tuner
Most in-dash CD players have AM/FM playback allowing you listen to your favorite local radio stations.
Yes
FM Presets
The number of FM radio stations that can be stored as presets.
18
AM Presets
The number of AM radio stations that can be stored as presets.
12
CD-R/RW Playback
This feature refers to whether or not the CD player will play finalized CD-R discs and/or CD-RW discs.
Yes
MP3 Playback
This feature refers to whether or not the CD player will play discs encoded with MP3 files. To burn a MP3 encoded disc, use the "data" mode on your CD Recorder and finalize the session and/or CD.
Yes
WMA Playback
This feature refers to whether or not the CD player will play discs encoded with WMA files. To burn a WMA encoded disc, use the "data" mode on your CD Recorder and finalize the session and/or CD.

DVD / Video Playback
This feature refers to whether or not the receiver will play DVD (or other listed) video disc formats. Unless otherwise noted, the unit is not guaranteed to play recorded DVDs.
No

Expandability Features

Navigation
Built-in navigation is a convenient feature that allows the driver to receive driving directions and guidance.

Some in-dash head units are built-in with the navigation features, while others require an add on navigation box. Other navigation options include portable navigation units that you can take with you or attach to the dash of your vehicle.

No
Additional Audio/Video Inputs
These inputs enable the unit to receive an audio or video signal from a separate source. There are many different types of connections and ways to accomplish this. Most common are RCA Composite cables and 3.5mm mini-jack plugs.

RCA Composite Inputs
These are your typical red, white, and yellow RCA composite cables that are common among devices with audio and video inputs. The red and white cables are dedicated for audio. The red cable is for the right channel and the white is for the left channel. The yellow cable is specifically for the video signal. Because this type of auxiliary cable contains 2 channels of audio, it will support stereo sound.

3.5mm
This is commonly referred to as a mini-jack or a headphone jack. It is a 3.5mm plug that transfers audio only. There is a right and left audio channel on the plug which allows for stereo sound playback.

3.5mm AV Input
These plugs look similar to the common 3.5mm mini-jack, however they carry a third channel dedicated for video.

Optional
This means that an auxiliary input is possible, but only with the use of an optional accessory. These optional adapters will sometimes use the CD Changer port or other port on the back of a unit that might restrict the use of other expandability features. These accessories are typically sold separately.

Front 3.5mm
Audio/Video Outputs
Audio/Video outputs are typically used to connect an overhead monitor to an aftermarket stereo. This is the number of A/V outputs that the item has. These outputs are usually RCA Composite cables.

RCA Composite Outputs
These are your typical red, white, and yellow RCA composite cables that are common among devices with audio and video inputs. The red and white cables are dedicated for audio. The red cable is for the right channel and the white is for the left channel. The yellow cable is specifically for the video signal. Because this type of auxiliary cable contains 2 channels of audio, it will support stereo sound.

No
USB Input
This feature refers to whether or not the receiver features an input to connect a USB device via standard USB or mini-USB. The USB input may be a connection on the front or rear of the unit with an extension cable for connecting devices to the receiver. Some units have an optional input that allows for a USB adapter to be purchased separately and used with the unit.
No
iPod Audio Integration
This refers to whether or not the receiver can connect to an iPod and allow for audio control and playback of the iPod through the head unit. Head units that have iPod connectivity allow your iPod to be connected and controlled via the head unit, and they will typically connect through the USB input combined with your standard iPod-to-USB charging/connection cable. We encourage you to read the description of the head unit to see if an adapter is required or included, or if you can simply use your own iPod-to-USB cable.
No
Satellite Radio
This feature signifies whether or not the receiver is compatible with XM or Sirius Satellite Radio. "Optional" means while the receiver is capable of SIRIUS/XM playback and connectivity, you will still need to purchase an additional satellite tuner, adapter, and/or antenna.
Optional - SIRIUS or XM (Accessory required and sold separately)
HD Radio
This feature refers to whether or not the receiver is capable of receiving high-definition digital HD Radio broadcasts by either a built-in HD Radio tuner, or more commonly with the purchase of an optional HD Radio tuner box. Receivers which are HD Radio Ready generally require an additional purchase of a separate tuner.
Optional
Bluetooth Connectivity
This feature refers to whether or not the head unit is able to connect to a hands-free Bluetooth device. Head units that are Bluetooth ready typically require the purchase of an optional adapter or accessory that connects to the rear of the head unit. This optional accessory allows you to accept phone calls through your head unit and speakers. Some head units have built-in Bluetooth hands free capabilities with an included remote-mount microphone or built-in microphone.
No
Steering Wheel Control Compatible
In order to retain a vehicle's factory steering wheel remote controls, a wired-remote input is needed on the aftermarket stereo.

If "Yes", then the aftermarket stereo is compatible with steering wheel remote controls. If an additional accessory is required for the steering wheel controls to work properly, a compatible piece will be listed.

Yes (Accessory required and sold separately)
CD Changer Controls
This feature signifies whether or not the receiver has the ability to control a CD Changer. If a receiver supports this function, it is usually compatible with a same-brand CD changer without the need for an extra adapter.
No
Rear View Camera Input
Indicates if an in-dash multimedia unit has a dedicated video input for rear view cameras. These inputs allow you to plug the camera to the back of the unit to receive the cameras video signal. Usually the camera signal is transferred through an RCA cable connection.
No
Memory Card Reader
Whether or not the receiver has a built-in input for removable memory cards such as SD (Secure Digital) cards or MMC (Multimedia) cards.
No

September 20, 2011

This head unit has been a big mistake of a purchase. After 4 years with my old Kenwood working just fine I wanted an auxiliary input. The Sony has come to a fast death in one season on the lake. Keep in mind I dry stack my boat and take the face plate off every use. The controls started periodically working within 2 months and it completely stopped working after 5 months. I used it maybe twice a week.

I currently have the CDX-M30 on a 05 FLHT, It works GREAT. The radio has more than enough power with the factory speakers. It plays CD-Rs, MP3s about anything you put in it. It is very easy to setup and operate. I also purchased the small remote control. It was easy to mount on the handlebar and works great. Would I buy this radio again? You bet i would, in a heart beat.

I replaced another Sony head unit with the CDX-M30 and the controls and functions are much more straight forward and easier to use, sound is clear and plenty of power from the unit, fully water-proof for a marine application. I would highly recommend this unit for someone who is challenged with trying to remember from season to season controls on one of the earlier models of head unit's, this one is straight forward and simplistic yet has all the features one wants and very stylish.

September 7, 2011

I purchased the Sony CDX-M30 to replace another Sony radio on my boat. The installation and wiring followed the old unit and, in my case, was done in about 10 minutes! The scrolling information is visible from my viewing angle as the previous Sony wasn't. There are not too many bells and whistles, but for listening to a CD or music while out on the water, this unit fills the bill perfectly.

I would recomment this product.
